If it is plugged in at all, it turns off and on by itself every 3 seconds, tried different jacks, de-batteried the remote just in case, checked to see if the on/off button was stuck. nothing. I dont have the $ to buy a new tv, so I am hoping to avoid chucking it in the garbage, can you help?

Re: Wierdness with the TV
OK - the bad news - like most electronic gadgets these days your TV when plugged in sits in a state where its using electricity waiting for you to push the remote button such that it can jump into life.
This means that there is a circuit in the TV that specifically energises when you push the remote on button and that kicks in a transistor to energise a relay that turns on the juice to get the TV going. Sounds like there is something in that energising circuit that has broken down, perhaps a resistor that is not a resistive as it used to be or a capacitor that is leaky and as a result the circuit is performing the signal to turn the relay on and loosing the capacity to keep the main power relay energised and then the relay is turning off, until the capacitor recharges and it is re energising the main power relay again.
The problem here is that there is no way that you are going to find that faulty component on your own without a wiring diagram, and oscilloscope and a knowledge of electronic design.
You could look up in the yellow pages TV repair and talk to some one over the phone to get an understanding of what may be the problem and a guideline on what they think it may cost to repair. It shouldn't be too much but if they give you the story of lots of dollars you could ask how much to just solder the relay such that the TV comes on straight away when you plug it in rather than having to use the push button or remote to turn it on. It by passes that circuit - its a little more harsh on the electrics and it means you have to plug and unplug the set to turn it off and on but its an option if you can't afford a new one.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

You must match the TV's input connections and the Roku output on your remote. This means if the Roku's output is connected to your TV's "HDMI 2" (or A/V 2, etc.), you must be able to select HDMI 2 (or A/V 2, etc) on the TV - either with your remote or pressing a button on the TV itself.
Sometimes, the TV will skip over unused inputs when it was first set up. This is done to reduce the number of button presses to go from say "HDMI 1" to "HDMI 4" by programming OUT the HDMI 2 & HDMI 3 choices.
You'll need to program IN the input that your TV uses to connect the Roku if it isn't already available. You MUST connect cables properly if not using HDMI. RGB is Red-Green-Blue and must be connected to RGB jacks at the Roku and TV for a picture and the the White & Red (left and right) audio must connect the the corresponding Red / White audio jacks - or it will provide strange results.
Make sure the power plug is connected to an outlet that is ON and connected to the power jack on the Roku box itself. Unless you have a defective Roku box or TV, it SHOULD work. You can try using a different HDMI or A/V jacks on the TV to determine if it is the TV jacks or not.
First of all, did you put new batteries in the remote control? That usually solves the problem, because when the batteries get weak the output infrared signal also gets weak. With a new universal remote control, there is a booklet containing the codes to use for many different TV receivers. If your specific TV model is not listed, try using one that appears to be similar to it. If that does not work, try turning your TV on with the new universal remote. If you can turn it on, then you may be able to have the universal remote program itself by interacting with your TV. Turn it on and hold the remote so that it points to the TV set and hold it there for about 30 seconds. Then try turning the TV off and on again and try to use the channel change feature. Try this a few times to give the TV and the remote a chance to talk to each other. Keep the remote pointed toward the TV.
Press the the cursor key up followed by down and power the TV off with the remote or the TV itself. Please use the original remote for this. Unplug the TV for a few seconds...replug and power the TV on. The second thing to try...press the cursor key left followed by the right key. Power the the TV off with the remote or the TV itself. Unplug for a few seconds...replug and power up the TV. Some of these TVs left the factory in the service mode. The fix is pretty simple. Thanks asking and show a few hands of support!
the "TV" button and then press the "Power" button on the remote. If the
TV turns on, your remote was just switched off of TV mode.

the batteries disconnect from the inner connections.

in. This will reset the TV in case a power surge caused the TV to
the batteries with new ones. Do not use old batteries from a different
device in your house because if the batteries do not work, you won't be
able to determine anything because those batteries may not have enough
juice to power the remote. Keep in mind that different devices have
different needs, so the batteries may have had enough power for
something else to work but not enough for your remote.
the batteries to see if they are inserted in the right direction. It's
possible that someone dropped the remote, the batteries fell out and
then were inserted incorrectly.
Press the "Power" button on the TV set to determine that the TV is not dead. A dead TV will not turn on from a remote.
Program the remote to another TV. If the second TV works from the remote, the problem is with your TV's remote signal receiver
Try switching the cables connected to the TV to your Wii, plug those 3 pronged cords into a different side. And about the remote thing, Im not 100% sure but i think you might have to open the battery compartment and press the red button to sync with the Wii.
My LG TV stopped responding to the remote. A very helpful repair technician told me to stick a head phone jack in the sensor jack on the back of the TV a few times to clean out the contacts. Now the remote control works fine.
you need to program your remote control. take the battaries out. and maually turn the tv on. then hit the source you want to view. for example, I want to control the tv set. I push, code search and hold it then push the source button and then release the source button and then release the code search button. now, aim at the tv and then keep pressing power button till it goes off. when the tv is off, hit return or set or something like that.( every remote has different calling for it but still the same function) it should work. try it and let me know.
